The Astrophysical JournalRecent Sun-as-a-star studies have shown that postflare loops can manifest as a secondary peak in the H α light curve, suggesting that stellar postflare loops are detectable.

Medicinal Research Reviews, EarlyView.ABSTRACT Chitinase‐3‐like‐1 (CHI3L1, also known as YKL‐40) has been recognized as a biomarker of inflammation and tissue remodeling and has now emerged as a pseudoenzymatic immune checkpoint. Recent structural, immunological, and translational studies redefine it as an active regulator of immune suppression rather than a passive disease marker. Despite

Thermal X-rays from stellar flares - Reevaluation of scaling from solar flares
The Astrophysical Journal, 1976 We suggest that, close to the time of maximum luminosity in both solar and stellar flares, the ratio of thermal X-ray luminosity, L/sub x/, to optical luminosity, L/sub v/, is given by the ratio of radiative to conductive energy loss rates from the X-ray flare plasma.

X-ray-heated models of stellar flare atmospheres - Theory and comparison with observations
The Astrophysical Journal Supplement Series, 1992 A sequence of five model atmospheres consisting of the photosphere, chromosphere, and transition region is computed. The models represent the response of the gas in a magnetically confined loop to intense flare energy release. It is assumed that the energy release is confined to the corona, and the effects of chromospheric evaporation and indirect ...

A radio jet from the optical and x-ray bright stellar tidal disruption flare ASASSN-14li [PDF]
Science, 2016 Transient radio jet from a black hole When a star passes too close to a supermassive black hole, it gets ripped apart by the gravitational forces. This causes a tidal disruption flare as the material falls into the black hole. van Velzen et al.

The Astrophysical JournalFluorescence line diagnostics of the Fe K α line at ∼6.4 keV observed in both solar and stellar flares can constrain the latitude and size of the flare loop, even in the absence of imaging observations. However, they are hampered by the unresolved origin

Senotherapeutics for Knee Osteoarthritis
Medicinal Research Reviews, EarlyView.ABSTRACT Osteoarthritis (OA) is a chronic disease that imposes a significant economic burden and deteriorates quality of life. Nevertheless, current therapeutic options for OA are limited to symptomatic remedies. As such, there is a high interest in novel methods for treating or preventing OA.

Short-Duration X-ray Transients Observed With WATCH on Granat: Are Some of Them Related to Stellar Flares? [PDF]
International Astronomical Union Colloquium, 1995 AbstractDuring 1990-92, the WATCH all-sky X-ray monitor on GRANAT has discovered 6 short-duration X-ray transients. We discuss their possible relationship to peculiar stars. Only one source, GRS 1100-77 seems to be related to a T Tauri star.

Scalable Room‐Temperature Terahertz Graphene Cameras
Small Methods, EarlyView.ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...
